The Federal Trade Commission is conducting a roundtable discussion to look at possible restrictions on car dealers.  This is regarding defective auto sales, especially in Yo-Yo sales.  This is where the dealer misrepresents to you that your financing has been approved and then weeks later after you have signed all the papers, tells you that the financing did not go through, and you will need to sign a more expensive contract.  You have a voice!  Comment at the link below.  The deadline is April 1, 2012.
